On this date in 1945, stripped down to his socks and underwear, 35-year-old truck driver and double murderer Charles Silliman was gassed in Colorado’s death chamber. He died for the murder of his wife, Esther Corrine Silliman, and their four-year-old daughter.

Charles and Esther had been married for nine years and didn’t have any relationship problems that anybody knew about. After dinner on January 22, 1944, he poured her nightly glass of brandy. He also gave a small amount to little Patricia Mae. Both mother and child became violently ill and quickly expired.

Charles said he had no idea what had caused their deaths, and suggested food poisoning as a possible answer. When the cops arrived on the scene, they found the grieving husband and father studying his wife and daughter’s life insurance policies.

The police were suspicious, especially after Charles began weeping and pulled out a handkerchief marked with lipstick. He said the lipstick was his wife’s, but … she never wore makeup.

Chemical analysis showed the brandy had been laced with strychnine, and a bottle of the poison turned up hidden in the tire kit in Silliman’s car. The police theorized he had committed the murders to collect on the insurance and be with “a woman whom he met in a beer tavern in Denver and later … while his wife was absent, he rather frequently visited.”

Charged with murder, Silliman admitted to the poisonings and said he and his wife, plagued by poor health and debt, had jointly decided to commit suicide and take both their children with them — but that he chickened out and was unable to go through with it. (Son Charles Jr. was not harmed, as he was living with his grandparents at the time of the murders.)

Silliman was tried for his wife’s murder only, and he told the jury about the unfinished suicide pact. The prosecution pointed out that, even if his story was true, the deaths of Esther and Patricia still constituted first-degree murder.

His insanity plea didn’t go anywhere either. “We are convinced from the record,” ruled the appellate court, “as the jury must have been from the evidence, that defendant’s insanity was an afterthought and conceived by him as a means of escaping the penalty which, under the evidence, he merited.”

Silliman did, however, gain an extra two hours of life: executions at the Colorado prison normally took place at 8:00 p.m., but at that time there was a Chamber of Commerce banquet going on and 550 guests were chowing down on turkey. The warden delayed the execution until 10:00 p.m., after dinner was over and everyone had left the prison.

His last words were, “I do not fear. I am going to a better world.”

(An aside: elsewhere in the United States on that same November 9, 1945, Jesse Craiton and Noah Collins were electrocuted in Georgia for robbery-homicide, and Cliff Norman died for rape in Oklahoma’s electric chair.)
